"Hach"

Provides a simple, fast, economical method of pH measurement

The most widely used disinfectant for drinking water, chlorine is also important for sanitizing swimming pools, cooling towers, other industrial equipment, and in the treatment of municipal wastewater.

The Stream Survey Kit tests ammonia, nitrate, dissolved oxygen, pH, phosphate (total) and temperature.

Hach Paddle testers allow fast, easy screening of water samples, solid surfaces, and non viscous liquids where unsanitary conditions may exist. The paddle is a double-sided slide attached to the vial cap. Each side of the slide is used to perform a separate test. The slide has a molded-in grid for easy colony counting without opening the optically clear, leakproof vial. Paddle tester, total aerobic bacteria/yeast and mold (tryptone glucose extract agar/sabouraud dextrose agar).

Using silver nitrate titrant, this kit provides fast, accurate detection of chloride.

One of Hach's most popular test kits, it uses the simple, low-cost color disc method.

Low dissolved oxygen levels in surface water systems usually indicate serious pollution

Kit provides measurement of ortho- (reactive) and meta- (condensed) phosphate (requires hot acid digestion).

Most natural waters range from pH 4 to pH 9, but commonly are above pH 7 because of carbonates and bicarbonates (alkalinity).

Water hardness is caused almost entirely by calcium and magnesium ions. Other di- and trivalent metals have a similar effect, but usually are not present in high enough concentration in potable waters to cause problems. Hardness increases soap consumption in laundries and causes scale in boilers.

Designed for testing ammonia in freshwater or seawater, this kit's color disc method offers low-cost, fast, reliable results in an easy-to-carry kit.

Simple, low-cost color disc method is the most accurate visual test kit method

Model HA-4P MG-L is a hardness, total and calcium (magnesium by difference) drop count titration/EDTA test kit with a range of 20-400 mg/L

Using the simple color disc method, this kit measures Iron (medium range - 0.2-10 mg/L) and contains 100 tests.

Carbon dioxide test kit with drop count titration covers ranges of 1.25-25, 2-40, and 5-100 mg/L as CO2, with increments of 1.25, 2, and 5 respectively. Includes rugged carrying case, prepackaged reagent set, detailed instructions, and all apparatus you need for fast, easy, and accurate carbon dioxide test results in the field.
